Abstract
We present the use of angle migration or generalized Radon transform (GRT) in 4D imaging. Illumination compensation at the imaging point allows stable imaging of 4D effects given data of equivalent coverage, but without any regularization or 4D binning in the preprocessing. The ability to fully control imaging contributions enables reducing noise contributions. Here, we show first results of using the algorithm for 4D purposes on synthetic and field data.
